Summary :

Potential Controlled (POCO) Laser is a new type of laser which utilizes a character that the lasing gain effectively increases and the threshold current level can be reduced by putting a large number of holes into the active layer. The basic idea of this laser is very close with the so called modulation doping in the multi-quantum-well structure. In this paper, the optimum configuration of the POCO laser is theoretically examined in detail. Possibility to get a very low threshold current lower than 100µA is predicted.
